Questions and Answers for TUSA Lead Battery For Diver Propulsion Vehicle:

  • Roger:

    I have a Tusa SAV-7 dive scooter. There is no lead dive plate under the battery but it is still too negative. Battery in it weighs 19.2 pounds. Is there anything I can do to add buoyancy to the unit. Guessing around 4 pounds. I have heard about a buoyant vest but unable to find. Thanks, Roger

  • Picot:

    Is the Elite of the same construction and material as the original Oceanic? That DPV has a max depth of around 160... the Elite considerably deeper. Does it have both static and compression seal for the top mating to the bottom? I have an old one that has been adapted for deeper use than the original, but I am considering something newer. JPC

SAV-7EVO-Battery - Lead Battery for TUSA SAV7

Dimensions: 5" x 7" x 6.5" (or 125mm x 175mm x 167mm)

Capacity: 10Ah (DC 24v)

Charging the battery (in case of lead-acid battery)

STEP1 Preparation for charging,

Please stand the scooter vertically on the propeller cover.
Make sure it's on a flat stable surface so that it cannot fall over and cause
damage to the propeller cover and blades.
If the scooter is wet, wipe all moisture off completely.

STEP2 Unfasten the locking buckles.

Unfasten four locking buckles on the body seal. A locking mechanism is
attached to the locking buckle to prevent it from releasing as a result of
unexpected shocks.
First, while pushing the square button in the center of
the locking buckle, lift the end of the buckle.
Next, after releasing the buckle hook, flip the buckle
downward. Release all four parts.

STEP3 Removing the battery housing.

It may be difficult to remove the battery housing (head Assy) due to negative pressure inside the body caused
by contact with the O-ring, temperature variation and other factors.
In this case, place the buckle latch under the locking hook and apply pressure with your thumb while pushing
upwards. Do this on both sides of the scooter concurrently to break the seal and easily release the
battery housing (head Assy).

Precautions concerning the handling of the battery housing (head Assy) after removal.
Silicon grease has been applied to the seals on the battery housing. Sand and other debris easily stick to this.
Be careful to avoid this situation.
Water leakage is caused almost entirely by sand or other debris adhering to the seal area.
Please put the battery housing (head Assy) in a safe clean place lying down
on the ribs located on its base.
Please do not place it on sand or on rocks etc.

STEP4 Releasing the battery connector plug.
Hold and squeeze the release levers on both sides of the battery connector
plug and pull upwards.
Altering the battery connector plug in any way is very dangerous and should not
be done. Any alterations will cause unexpected trouble.
STEP5 Removal of the battery.
Hold the battery firmly with both hands and lift it away from the body.
Place in on a clean and dry flat stable surface.
The battery is quite heavy, so be careful not get your fingers pinched or to
drop it onto your feet.
STEP6 Connecting the single-purpose charger to begin recharging.
You must use the correct single-purpose charger suitable for the type of battery being used. In
this case, we are showing the LEAD-ACID battery as an example.
Please refer to the handling manual that is attached to each product about the battery.
First, connect the AC (alternating current) plug of the charger to a domestic outlet.
Next, connect the DC24V output connector from the
battery to the connector receptor plug on the
charger. The charging will automatically start upon
connection after the power is turned on at the
domestic outlet.

The connector is polarized, so when connecting, insert in a direction so it will smoothly enter the connector

STEP7 Disconnect the charger when charging is completed.
The battery charger automatically changes into trickle
charge mode after charging is complete however please
avoid leaving the charger connected after the charge
lamp becomes green.
At first, turn the power off and remove the
AC plug from the domestic outlet.
Next, remove the battery connector.

STEP8 Charge completion.

Please do not set the battery into the scooter for at least 30 minutes after completing the charge as the battery
continues to emit hydrogen gas. Please keep clear of an open flame.
